PHOTOGRAPHlC-PLATE HOLDER.

SiPECIFlGATEQN forming part of Letters Patent No. 328,512, dated Qatober 20, 1885.

Application filed February 26, 1885.

To all? whom, it may concern Be it known that I, OSCAR M. PAUSOH, a citizen of the United States, residing at Newark, inthe county of Licking and State of Ohio, have invented a new and useful Photographic-Plate Holder, of which the following is a specification.

My invention relates to improvements in photographic-plate holders with which one or more exposures are made upon the same plate or sensitive film. Heretofore one or more exposures have been made by sliding the plateholder bodily from right to left or up and down on the back of the camera by means of asliding frame,which has the disadvantage of often leaking light on account of being but loosely attached to the back of the camera. My plate-holder is intended to be held firmly to the camera by the usual construction of non-sliding-back cameras, the shifting of the plate being effected directly inside of the plateholder itself. I attain these objects by mech anism illustrated in the accompanying drawings, in which Figure 1 is a vertical view of the entire plate-holder; Fig. 2, a section of the rod G; Fig. 3, the spring which engages the rod, and Fig. 4 the spring H, which holds the lower part of the frame 0 in place.

Similar letters refer to similar parts throughout the several views.

The frame A is the outer frame of the plateholder; B, the lid; 0, the sliding frame which holds the plate by means of the spring E. This frame is reversible, as indicated by the arrow.

The sliding of the frame 0 is effected by the rod G, as shown in the drawings. The rod G passes through a hole in the frame A. The hole is lined with velvet or any other soft substance Serial No. 157,066. (No model.)

which will admit of easy passage of the rod G and yet make a light-tight joint. The single or double lines around the rod G serve as guides to the operator in pushing or drawing the rod. The head of the rod G being pointed, it engages the spring F automatically and in this way secures the rod G firmly to the frame 0.

Two edges of the frame 0 are grooved to fit loosely the corresponding strip in the frame A when the frame 0 is either in the position shown in the drawings or reversed, as indicated by the arrow, which serves to hold the frame 0 at its upper edge and permit of its sliding.

In reversing the frame 0 the spring F is to be slightly lifted by the thumb-nail, the rod G drawn far enough to disengage it; next the spring H is to be pressed down, (see Fig. 4,) which allows the frame 0 to be removed and reversed.

Fig. 3 shows the spring F, of which there are two on the frame 0.

The letters D indicate the slide, which is drawn after the plate-holder is attached to the camera, so as to admit the light to the plate.

I claim The herein described photographic plate holder, consisting of the outer frame, A, lid B, reversible plate-slide 0, provided with spring E, rod G, arranged to engage with one of the springs F upon plate-slide G, and the securing-spring H, the whole combined, arranged, and adapted to permit the shifting of the plate for double exposures, substantially as shown and described.
